일산화탄소 위해에 관한 연구 제2편 제환경하의 일산화탄소 오염도 및 중독양상ㅇ 대한 조사연구

Abstract

This investigation was undertaken to find .out the degree of the CO pollution in various environments in relation to various environmental factors concerned. As the objects of the survey. 440 places in SundongGu area including the private living room. restaurant. barber shop. beauty shop. tea-room. laundry etc .. were selected by a random sampling. The measurement of the blood Hb-CO of the subject exposed to the COpolluted air was made for 96 persons. The results are as follows. 1. The private living room showed pretty high degree of CO pollution. The pollution rate was 27.9% in the low-grade home group and 42.0% in the poorest home group. 2. The highest degree of the CO pollution was found in the kitchen of the Korean wine house. It showed average 231. 2 ppm and the next was the kitchen of the restaurant where average 173.0 ppm was detected. The degree of the CO pollution was almost nearly 100% where the briquette was openly burned. 3. The environmental conditions of the living room such as paper-coating status of the wall and floor. chimney. and the structure of the room were much more related the degree of the CO pollution. The open uses of the briquette and poor air conditioning system were the main causes of the CO pollution in otherenvironments. 4. Blood Hb-CO concentration of the subjects expo sed to CO-polluted environments were measured by the method estimating blood Hb-CO by breath-air analysis. The results showed maximum 12.5% HbCO and the minimum 5% HbCO. Many subjects exposed to high degree of the CO pollution complained persisting headache. atonia and gastro-intestinal troubles.
